LAMP-SHADE HOLDER.

Specification of Letters Patent. Patented Sept. 10, 1918.

Application filed April 17, 1918. Serial No. 229,038.

To all whom it may concern; Be it known that 1, MAX KossMANN, a citizen of the United States of America, residone of the elements-of the lamp assembly to perform its function in supporting the said inverted globe.

In the accompanying drawing, to which reference will be had, in connection with the following'detailed description:

Figure 1, illustrates a sectional View partly in elevation of a lamp assembly a part of which constitutes my improved holder;

Fig. 2 is an enlarged fragmentary sectional view, the section being taken on a line 2-2 in Fig. 1 before the cap is presseddown; and

Fig. 3 is a perspective view of my' improved holder.

The type of lamp to which my inve'ntion applies, comprises an inverted globe 4, a reflector 5 therefor, and a cap 6 which supports the lamp assembly, said cap being attached to any suitable suspension means, a tubular conduit 7 for instance. The cap 6 is of the usual cupped formation, having a depending side-wall 6 and asocket 8 for the attachment of a suitable supporting medium for the lamp assembly. The' cap 6 will be'provided with the usual clamping screws 9 which pass through the wall 6 and engage'the neck 10 of the reflector 5. As this is a common expedient, it has not been illustrated in greater detail.

My improvement is embodied in a holder or bracket 11 consisting of a plurality of yieldable or flexible arms 12, 13 and 14, se-

cured at their lower end to a cup-shaped base-member 15, to which a cap 16 is connected by means of a threaded stud 21 and rotatable nut 17. The lower end of the lower globe 4% is supported by the lower. cap 16. To insert the lower end of the globe in said cap, the nut 17 will be manipulated.

to permit the lower cap 16 to be pulled away from the lower end of the holder 11, sufliciently for the insertion thereinto ot the lower end of the globe 4, after which the cap 16 will be adjusted and maintained by the nut 17.

The upper end of each arm 12, 13 and 14: is bent over or hooked as at 18 to provide a downwardly extending yieldable projection 19 to engage the flange 6 of the upper cap 6. As can be seen in Figs. 1 and 2, the hooked ends of the arms engage the upper beading or edge 20 of the globe 5, the yieldable extensions 19 being located exteriorly of the reflector 5 and in engagement with the flange 6 of the cap 6. When the lamp is assembled, the cap 6 will engage the projections 19, said projections being at such a time under a slight tension; hence the holder-11 will be firmly held against rotation or jarring. Owing to the fact that -the upper end of each arm 12, 13 and 14 is thus firmly held, the holder can be adjusted to position the lower globe centrally of the reflector 5. To adjust. the holder, the arms 12, 13 and 14 will be bent or manipulated in any desirable manner. The yieldable projections 19 of the hooked ends of the arms 12, 13 and 14, are provided with lips 22, which engage the lower edge of the flange 6 of the cap 6.

' The particular object of my invention is to provide a holder-arranged to cooperate with one of the elements of the lamp assembly, preferably the upper cap, that will be firmly held against a shifting action after the upper cap has been applied to the re-. flector and secured by its set-screws.

It will be apparent from an inspection of Fig; 2 that the extensions 19 of the hangers 12, 13 and 14 will be forced inwardly by the flange of the cap when said cap is pressed down, thereby forcing the adjacent ends of the hangers firmly into contact with the edge 20 of the reflector 5 and causing the heading 23 to enter the recess 24. adjacent the outer end of the extensions lfl, thereby preventing premature separation of the cap and holder. irrespective of the set screws, which might loosen,

What I claini as my invention is: Signed at New York city, N. Y., this In a shade-holder, a plurality of flexible 12 day of April, 1918.
